Apr 7, 2025 · A Queue Data Structure is a fundamental concept in computer science used for storing and managing data in a specific order. It follows the principle of "First in, First out" (FIFO), where the first element added to the queue is the first one to be removed.

A queue is a useful data structure in programming. It is similar to the ticket queue outside a cinema hall, where the first person entering the queue is the first person who gets the ticket. In this tutorial, you will understand the queue data structure and it's implementations in Python, Java, C, and C++.

What is a Queue? A queue is a linear data structure where elements are stored in the FIFO (First In First Out) principle where the first element inserted would be the first element to be accessed. A queue is an Abstract Data Type (ADT) similar to stack, the thing that makes queue different from stack is that a queue is open at both its ends.

A queue is a data structure that can hold many elements. Think of a queue as people standing in line in a supermarket. The first person to stand in line is also the first who can pay and leave the supermarket. This way of organizing elements is called FIFO: First In First Out. Basic operations we can do on a queue are:

Jan 15, 2025 · What is a Queue in Data Structures? A queue is an ordered list in which insertion is done at one end called REAR and deletion at another end called FRONT. The first inserted element is available first for the operations to be performed and is the first one to be deleted. Hence, it is known as First In First Out, FIFO or Last In Last Out, LILO.

Jan 25, 2025 · Queue in data structures is a linear collection of different data types which follow a specific order while performing various operations. It can only be modified by the addition of data entities at one end or the removal of data entities at another.

A queue is one of the fundamental linear data structures in computer science, widely used for storing and processing data in sequential order. Following the First In, First Out (FIFO) principle, it ensures that the first element added is the first one to be removed, making it ideal for scenarios where order is crucial.

Feb 20, 2025 · What is Queue in Data Structure? A queue in data structures is a fundamental concept where elements are arranged in a sequence, and operations are performed based on the First In, First Out (FIFO) principle. This means that the first element added to the queue will be the first one to be removed.

Queue in Data Structure is a linear data structure that follows the First-In-First-Out (FIFO) principle, where the first element added to the queue is the first one to be removed. It operates with two main operations: enqueue, which adds an element to the end of the queue, and dequeue, which removes an element from the front of the queue.
